I know Salmon bellies are good bait for the large left eyed Pacific Halibut but our smaller right eyed California halibut are not as opportunistic and prefer live bait.
If your into hoop netting for lobsters I would cut the bellies into strips and add a small portion into the bait cages of your nets. The oil in the salmon bellies will travel a long way and attract bugs that might miss other less oily baits.
I envy you. I've not had any salmon in my freezer for almost a decade.
